Voyantic System Measures Effects of Repeatedly Bending a Tag

Voyantic Ltd., a provider of RFID measurement solutions based in Finland, has announced Bendurance, a testing system designed to analyze the changes induced to ultrahigh-frequency (UHF) RFID tags' operation sensitivity due to repeated bending.

Voyantic's Bendurance system

With Bendurance, the tag samples are stressed by running them in a loop through a set of bending rollers, and their performance is then evaluated via Voyantic's Tagsurance ultrahigh-frequency (UHF) production testing system (which can detect and flag UHF tags that do not meet their specified characteristics), using communication tests at several frequency and power-level combinations. In addition to bending, the samples may also be subjected to compression stress during the run.

The Bendurance system operates in multiple motion and test modes, according to Voyantic. Tags can be stressed in continuous motion, and can be monitored constantly at a chosen frequency. A more thorough analysis can be performed at intervals, by stopping the continuous stress after a set amount of rounds and then running performance tests. The test results are logged into a data file, to be handled later for statistical analysis purposes. The threshold sweep results can be analyzed post-test using a separate software tool known as Tagsurance Sweep Data Analyzer.

Voyantic is showcasing its RFID test and measurement solutions in booth 810 at this week's RFID Journal LIVE! conference and exhibition, being held in San Diego, Calif.
